Get to know the Power System in One Piece

Source: One Piece (Anime)

 Every "shounen" manga in the fantasy genre is unique in the way things work in that world. In the world of One Piece, there are things that magically and wonderfully happen in this manga. In the world of One Piece, there are currently 2 sources of power that prevail in the pirate era. With these two powers, these people can search for One Piece treasures. What are these 2 powers, let's take a look?.

1. Devil Fruit

Devil Fruit is a mysterious and distinctive fruit scattered around the world, known for giving the eater special abilities and powers but with the side effect of losing the ability to swim.

Devil Fruits are very numerous. It is estimated to number in the hundreds with each having different powers, ranging from the (seemingly) ordinary to those with the power of mass destruction. Devil Fruits are broadly categorized into three classes: Paramecia, which offers a wide array of strange abilities, Logia, which gives its users the power to become and control natural elements, and Zoan, which allows its users to transform into animals or animal hybrids.

Many of the most important people in the world are devil fruit users, especially among the Three Great Powers. Therefore, in addition to its rarity, Devil Fruit is highly sought after; a single Devil Fruit can be worth hundreds of millions of Berries and some parties are working to artificially create it so that it can be mass-produced for warfare purposes. A person/beast/thing can only consume and gain power from one Devil Fruit, except for one person.

Like Monkey D Luffy is a paramecia devil fruit eater (originally) Gomu-gomu no mi, which last year a fact was revealed that Luffy's devil fruit was Zoan Awakening: Sun God Nika mode. From the beginning of the chapter, we know that Luffy's power is a rubber fruit that can lengthen his entire body. After the story developed for about 25 years, we were treated to the fact that his strength was not limited to rubber but the imagination of the devil fruit user depending on the creativity of the user.

2. Haki

Haki 覇気 (meaning "Ambition"?) is a mysterious power found in every living being in the One Piece world. It is not much different from normal senses. However, most people are unaware or fail to awaken them. In general, there are two types of Haki for everyone, given the right training. However, there is a third type of haki and only a select group of "chosen ones" can possess this haki. In simple terms, Haki is the ability to sense spiritual energy and defeat enemies. 

According to Silvers Rayleigh (Luffy's Teacher) "Haki is the power latent in every human being, the "instinct", the "fighting spirit", and the "power to compel". Those are all sensations that humans definitely have. However, most humans are unaware of that power. Or maybe they spend their lives trying to draw it out, but still can't." There are three types of Haki .

• Kenbunshoku Haki, which gives users a sixth sense of the world around them and limited precognitive abilities.[3] Users can hone their skills to such an extent that they can predict the future, as seen with Charlotte Katakuri.[14] Enel uses her Devil Fruit, the Goro Goro no Mi, to significantly increase her radio detection range.[15]
• Busoshoku Haki, which allows users to use their spirits as armor to defend against attacks or make their own attacks more powerful.[3] Users can learn to use the Koka Technique over their entire body and \or weapon.[16] Furthermore, when clashing with other Busoshoku Haki users, users with lower levels will feel the impact to some degree, ranging from swelling.[17], physical changes.[18]
• Haoshoku Haki, a rarely used one-in-a-million type of Haki that grants the user the ability to defeat the will of others.[3] Users of this type of Haki seem to be somehow ranked, as Chinjao claims that one can become "the pinnacle of all conquerors".[19]

Luffy has been practicing haki with Silvers Rayleigh who mastered 3 haki at once. He can already master Kenbunshoku and Bushosoku. While practicing Rayleigh already knew that Luffy had a rare Haoshoku power. This power can subvert living things that have low haki power.
